HINGE.

SPECIFICATION forming part of Letters Patent No. I731,389, dated June 16, 1903.

Application filed December 10,1897. Serial No. 661,358. (No model.)

To all whom if may concern:

Be it known that I, JOHN ST. AMAND, a subject of the Queen of Great Britain, residing at Brockton, county of Plymouth, State of Massachusetts, have invented an Improvement in Hinges, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

io My invention is an improvement in hinges, having for its object the provision of a hinge offering great resistance to longitudinal strains-that is, to strains lengthwise of the leaves of the hinge and transverse to the x 5 pintle thereof.

My hinge is primarily intended to be embedded in the wood or other material of the parts joined thereby, and at each end of the leaves of the hinge I provide outturned zo flanges which present a sharp angle, preferably a right angle, at their junction with the leaf or leaves composing that part of the hinge, this sharp angle preventing any Wedging action and holding into the wood with a 2 5 firm and extremely tenacious grip.

In the accompanying drawings, Figure 1 shows in perspective apreferred embodiment of my invention. Figs. 2 and 3 are side elevations of modified forms of my invention,

3o and Fig. 4 is a sectional view illustrating a manner of using my invention.

Referring to the drawings, the general shape and arrangement of the hinge, herein shown as comprising leaves a a', joined by a pintle a2, may be of any desired or preferred pattern convenient for the special purpose to which the hinge may be put or adapted. The ends of the leaves are provided with outturned flanges a3, and preferably there will 4o be four of these flanges, two extending in opposite directions at each end of the hinge, although it will be understood that one main object of my invention is to provide a sharp definite corner at c4, and therefore the specific location of the flanges may be varied.

considerably as well as their extent and particular shape may be varied.

In Figs. 1, 3, and 4L I have shown the flanges ai* as projecting perpendicularly from the 5o body vor leaves of the hinge and in Fig. 2 I

have shown the flanges CL3 as projecting backwardly over the leaves of the hinge, so as to form an acute angle therewith, the object of this modilication of my invention being to cause the hinge itself to hug into the Wood at each side thereof underany longitudinallypulling strain.

By having the flanges CL3 extended from the body or leaves of the hinge at a sharp angle of ninety degrees or less therewith they oder 6o a very powerful resistance to longitudinal strains, said longitudinal pull being distributed over the Whole section of the material included by the flanges, all the pulling'strain coming directly in longitudinal line with the hinge without causing anylateral movement or splitting tendency.

Referring to Fig. 3, it will be seen that I have provided a further strengthening fea ture in the form of a lateral offset a5, prefer- 7o ably projecting rearwardly therefrom, which prevents the outer end of the flange a3 from being bent and in the form shown absolutely prevents any backward deflection thereof under any strains, and preferably, also, I provide a depending lip or flange a6, which forms, with the opposite flange a3 andthe offset a5, a box-like rib or projection on the body of the hinge; and in case these are used in opposite pairs, as herein shown, the two 8o thereof constituting the pair coperate as a single T-shaped head or double shoulder for the hinge.

l My invention is intended to include the use of a single flange as or of opposite flanges, as is herein shown, and it includes the forming of these by oppositely bending, casting, or otherwise shaping the material constituting the hinge, or, if preferred, the hinge may be cast or otherwise formed with both of the op- 9o posite flanges a3 formed in one integral T- head, and this may be solid, or hollow, substantially as shown in Fig. 3. In the latter case I prefer to use a key or filling-block or pin a7, as shown -in Fig. 4, which wedges or holds the parts of the hinge which form the projections or ribs thereof out solidly and firmly into the wood or other material b in which the hinge is embedded.

I disclaim the form of hinge shown in Arroo nolds Patent No. 590,873, wherein a hinge is shown provided with circular enlargements at its opposite ends and adapted to be clamped between opposing surfaces of grooved boards. My invention is a hinge having sharply-defined angular projections or anges which get a tenacious grip in the material and prevent any possible wedge-like action under a longitudinal pull of the hinge. My hinge is intended to be driven edgewise into the wood or other material after a proper kerf has been sawed therein to receive the hinge with a driving fit.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is

l. As an article of manufacture, a hinge, comprising` oppositely extending leaves united at their adjacent ends by a hinge-pintle, and lying in the plane of the pintle, said leaves being provided with pairs of outturned flanges extending straight out from the plane of the leaves, and presenting at their junction with the body of the leaves a sharp angle less than an obtuse angle, substantially as described. i

2. As an article of manufacture, a hinge, having a narrow flange at the opposite extremities of the hinge-leaves, said flanges being parallel to the pintle and fiat or plane as distinguished from curved or rolled,and formset forth.

4. A hinge having a fiange at the extremity of a leaf of said hinge, said flange projecting perpendicularly to the plane of said leaf and forming at its junction therewith substantially a right angle, said flange having at its free end a lateral odset extending rearwardly therefrom at a sharp angle, a depending lip or flange at the free edge of said offset, and a iilling-block adapted to t snugly Within and against said projecting flange, oset and depending flange, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JOHNr ST. AMAND.
